22a all 'whom t may-concern.-

Beit known thatv l, Or'ifo Permian-NN, a citizen of the Republic of Switzerland, and a `:resident of Groton, county of Tompkins, and State of New York,'have invented cerand useful Improvements in Bar Mechanism for Type-Whiting Machines, of which the following is a'full, clear, and exact description.

This invention relates more particularly to i means for hanging the type-bars of visible or front-strike typewriting machines.

The `primary object. of the invention is to provide simple and ellicient hangers each adapted to individually hold a type-bar so that said type-bar and the hanger may bek removable, and so to construct the hanger that theparts comprising the same may be adjusted in the direction of wear Without taking the parts off the machine or the type-V bar supported thereby detached from said anger.

Another object of the invention is to provide a type-bar and hanger having relatively large bearing surfaces to Secure proper alinement, and to construct the bearing surfaces in such a Way that there VWill be very little friction. l

Other objects of the invention are to provide'hangers for type-bars which are substantially dust-proof yet permit the bearing and Wearing' surfaces 'to be properly lubricated; to provide hangers each adapted to hold a single type-har and so formed as to assume a curved or are-like arrangement v when placed in position, and to -provide simy structions of typewriting machines.

With these invention Will`rbe hereinafter la-rly described with reference to the accompanying drawings, which form a part and other objects in view, the

more particu-Y ed out in the claims at the end of the description.

In the drawings, Figure 1 is a fragmentary vertical section of a. typewriting'machine, showing one form of my invention 1 applied thereto. Fig. 2 is an enlarged vertical section of one of the hangers or brackets taken on the line II-H of Fig. 1, showing also one of the hangers in front elevation. Fig; Bis an enlarged fragmentary side elevat-ionof one end of the type-bar. i Fig. 4. is a sectional plan view of one of the type-bars, taken on the line lV-IV ofFig. 3. Fig. 5 isa sectional plan taken on the line V-V of Fig. 2. Fig. 6 is a vertical section showing a slightly dilferent form of means for pivotally supportinff the typebars. F ig. 7 is an enlarged iagmentary sect-ion, showing a diffrent form of means for taking up the Wear. Figs. 8 and 9 are sections showing different means for pivotally holding the typebar between the hanger members; and Fig. 10 is an elevation, showing the arrangement of a plurality of hangers looking at the rear thereof.

The frame 10 has a plurality of pivotally held key-levers 11 supported thereon which may be normally forced in one direction by springs 12, and at their inner ends are connected by links 13 to the type-bars 14. The type-bars 14 have type-heads 15 at their outer ends, and said heads, when the key-levers 1 1 are depressed, are forced up'- Ward against the platen 16, the latter' being suitably supported on a carriage 17 or other- Wise held on the machine. All of these parts may be of -the usual or of any preferred construction and arranged in any desired Way. Each type-bar 1l is held to a bracket or hanger 18, there being an individual hanger .for each typebar. This hanger 18 comprises two members 19 and 20. The mem ber 19 may be made somewhat heavier than the member 20 and has an angular or flange I portion 21 which is adapted to rest against the back plate or member 22 of the machine frame, and said angular portion is provided with threaded openings 23 which are adapted to be engaged by.. the threaded ends of screws 24 to removably hold the hanger to l of this specification, and will then be pointforming a space tion of the member v properly lit the opening l bearing rib v,which is adapted to receive the machine frame, and if 'the openingse through the machine frame ari-1A slightly larger than the screws 24, a vert-ical adjustment of said hanger may t-o cause the hangers when in position to assume a segment-al or curved arrangement as shown in F 1g., 1 0.

The member 2li-gis substantially rectangular in formandihas an oflset port-ion 25 26 between the said member and the member a flange or part 27 which is fastened by a screw 28 or otherwise to the member 19, and has a part 29 which will yield or spring and permit the olf-set 'portion 25 to move toward the member 19. At the upper por- 20 is a flange 30 through which is an opening, and passing through the opening is a threaded stem 32, the endl of which engages a threaded opening in the upper portion of the member 19. The head of the bolt or adjusting 1 device 32 may be hexagonal so that a wrench or tool may be made to engage sail head and rotate the bolt 'to force the portion 25 of the member 20 inward toward the member 19. As will be seen, the portion 25 eX- tendsoutward beyond the flange 30, so that when two brackets are placed side by side, a space will occur between the saine for the head of the bolt 32 sullicient for a thin wrench to be inserted for adjusting purposes.. i A head or pivoting end 33 is provided on each type-bar and this head serves to form a bearing portion fcnthe type-bar in the space 26 between the members 19 and 20. The head 33 iscircular in form and of a relatively large diameter, and has an annular 34 formed on one side thereof. The rib or bearing3l is integral with the body of the type-bar, and in forming the rib the body of the type-bar is depressed or tapered, at 35, from the rib gradually to the thickness of said body. A tapered opening 36 is formed inthe head 33 substantially centrally thereof when the type-bar is made and said opening is formed by forcing a part of the body of the metal outward.l as at 37. This serves to provide an extended opening a projecting pintle 38 formed as a part of the member 20. The pintle orbearing38 may be formed by forcing the metal inward and the outersurface thereof may be ground if desired to 36 in the head of the type-bar, themember 19 being also providedwith an opening 33a cent to the projecting part 37 so that the said'part 37 mayl extend into said opening without interfering with the movement of4 the type-bar, and to permit properradjustment of the member 2O and type-bar.

l be secured. l The flange or angular portion 21 is tapered,

19. This member 20 has l that the wear maybe taken up 31 of a bolt if desired adjel and in said opening is a As will be seen, the head 30 with the rib or portion. 311 forms a relatively largebearing surface with very little friction, and at the same time said bearing rib or surface may be forced into ner surface ofthe member 19 in case of wear, by rotating the bolt 32 which will force the projecting part 38 into the opening` 36 thus taking up 'any wear or lost motion that might occur. The bolt 32, screw 28, and

l pivot for the type-bar are in alinement so evenly and without removing the hangers. It will be seen also that the pivot bears onone side of the type-bar only while a relatively large concentric and plane bearing surface is provided on the other side of said bar. I

he parts so faras the openings, the typebar and the members of the hanger are concerned may be stamped from sheet metal, and when' being stamped to provide an opening for the. screw 28, themember 20 at the flange or part 27 may be depressed, form two projections 39 serving as dowel pins which are adapted to fit into openings t() in the member 19.

1n Fig. 6, the construction is substantially engagement with the -inf the same as that already described except thatinstead of the part 38 which is forced from the body of the member 20, a pin 41 the over the upper edge of the member 19 and which prevents drt and particles caused by the eraser from falling into the opening or space between the members 19 and 20.

Fig. 7 shows a-.construction substantially the same as that of the other figures except. as to the means for adjusting the two meinbers 19 and 2O relatively with respect to each other; In'l this form, the member 19 is provided with a flange 4:4. in which is a tapered opening 15 and this opening is adapted to be engaged by the tapered end 46 of a screw or bolt 117, the latter being provided with a head i8 for engagement by a screw driver, or the said vhead may be otherwise formed to be operated in any desired way. Then the bolt 47 is rotated, the tapered end i1G of said bolt by engaging with one side of the tapered opening 15 will force the member 2O inward to adjust and hold the type-` bar properly against the member 19.

The construction *shown in Fig. 8 provides an effective means for pivotally supporting the type-bar The type-bar head 33'has a tapered opening i9 which vis opposed to a tapered opening 50 in the hanger member 20,

ball 51. This ball is adju-stable with the member 20 andserves i scribed.

' stantially' the entire f2. The combination of as a pivot for the type-bar, otherwise the hanger may be constructed as already de- `In Fig. 9, as in the other views, the hanger may *constructed "and the members adjusted in any desired Way. Here the pivot 52 is in the form of a pin carried by the member 20, and said pin has its inner end hemispherical or ball-like which enters a tapered openingl in the type-bar head 33.

From the oregoingyit will be seen that simple and eliicient ineans are provided whereby a number of type-bars may be independently supportedin hangers so as to be removable; that said hangers are simple in construction and permit proper adjust ment to compensate for wear and to keep the type of the type-bars intproper aliiiernent;

that by constructing the hangers in the Inanner described, the cost .of assembling the type-bars and making the machine is sub stantially reduced; that the type-bars may have a relatively large bearing surface with a small amount of friction; that simple and elicient means is provided for'ad'justing the parts of the hangers individually Without re moving the hangers or without removing the typebars therefrom; t-hatsaid hangers are adapted for use in various classes of machines; that simple means is provided for pivotally holding the type-bars; that subhanger may be stamped from sheet' metal and thereby require very llittle hand work, and that a hanger is provided which is vdust-proof and which may be easily lubricated.
